A total of 904 weanling pigs were used to investigate the effects of 1) spray-dried porcine plasma (SDPP), 2) blends of SDPP and spray-dried blood meal (SDBM), and 3) added dietary methionine in a SDPP-based diet on starter pig performance. In Exp. 1, 534 weanling pigs (initially 6.4 kg and 21 +/- 2 d of age) were used to determine the effects of either 0, 2, 4, 6, 8, or 10% SDPP and lactose as a replacement for dried skim milk in the Phase I diet (d 0 to 14 postweaning). All pigs were fed the same diet from d 14 to 28 postweaning. Average daily gain from d 0 to 14 increased (linear, P < .01) with increasing SDPP. From d 14 to 28, ADG decreased (linear, P < .03) as level of SDPP fed during Phase I increased. However, for d 0 to 28, ADG was increased (linear, P < .01) with increasing SDPP in the Phase I diet. Feed intake increased with increasing SDPP from d 0 to 14 and d 0 to 28 (quadratic, P < .04 and P < .08, respectively); however, gain/feed (G/F) was not affected. In Exp 2, 298 weanling pigs (initially 5.5 kg and 19 +/- 2 d of age) were used to determine the effects of replacing SDPP with SDBM in the Phase I diet. Pigs were fed either a diet containing 10% SDPP or diets with SDBM replacing 25, 50, 75, or 100% of the lysine provided by the SDPP.(ABSTRACT TRUNCATED AT 250 WORDS)
总共904头断奶仔猪用于研究以下因素对断奶仔猪生长性能的影响：1）喷雾干燥猪血浆（SDPP）；2）SDPP与喷雾干燥血粉（SDBM）的混合物；3）在以SDPP为基础的日粮中添加蛋氨酸。在实验1中，534头断奶仔猪（初始体重6.4千克，年龄21±2日龄）用于确定在第一阶段日粮（断奶后第0至14天）中用0%、2%、4%、6%、8%或10%的SDPP和乳糖替代脱脂奶粉的效果。所有仔猪在断奶后第14至28天饲喂相同日粮。从断奶后第0至14天，随着SDPP添加量增加，平均日增重呈线性增加（P<0.01）。从断奶后第14至28天，随着第一阶段日粮中SDPP添加量增加，平均日增重呈线性下降（P<0.03）。然而，对于断奶后第0至28天，随着第一阶段日粮中SDPP添加量增加，平均日增重呈线性增加（P<0.01）。从断奶后第0至14天以及第0至28天，采食量随着SDPP添加量增加而增加（二次曲线，分别为P<0.04和P<0.08）；然而，料重比不受影响。在实验2中，298头断奶仔猪（初始体重5.5千克，年龄19±2日龄）用于确定在第一阶段日粮中用SDBM替代SDPP的效果。给仔猪饲喂含10%SDPP的日粮或用SDBM替代SDPP提供的25%、50%、75%或100%赖氨酸的日粮。（摘要截选至250词）
